As you get older, there are going to be a few more challenges, but thankfully I'm still feeling good.

I love the relays. Track is such an individual sport, so it's fun to do something together.

I don't have a sprinter's body.

I am a big believer in visualization. I run through my races mentally so that I feel even more prepared.

Everyone sees the glory moments, but they don't see what happens behind the scenes.

And as long as I'm passionate about the sport, I'm able to do that and I'm happy, then I would love to do another Olympics. I'm just going to see how I'm feeling.

I am a sprinter, and I love to go fast. It's very difficult for me to be patient and follow a race strategy or conserve energy.
